Is the internal ROM accessed with no-wait in the memory expansion mode?

Latest Updated:03/15/2012

Question:

Is the internal ROM accessed with no-wait under the following register conditions in the memory expansion mode?:
- PM17 bit of the PM1 Register is "0" (no-wait)
- CS0 bit of the CSR Register is "1" (chip select output enabled) and CS0W bit is "0" (with wait)

Answer:

Since PM17 bit is set to "0", the internal ROM area is accessed with no-wait. CS0W bit sets with or no-wait for the /CS0 area.
